Abstract:
La réalisation de la dosimétrie in vivo (DIV) en radiothérapie externe reste difficilement applicable dans le cadre d'irradiations conformationnelles avec modulation d'intensité (RCMI) où la mesure obtenue à l'aide de détecteurs ponctuels placés en entrée de patient est trop peu représentative de la dose réellement délivrée au volume cible. L'utilisation des imageurs haute énergie au silicium amorphe ("Electronic Portal Imaging Device", EPID) dans ce contexte est une alternative intéressante à condition de disposer en parallèle d'algorithmes permettant de convertir le plus précisément possible

Abstract:
The increasing use of intensity modulated radiation therapy (IMRT) to deliver conformal radiation treatment has prompted the search for a faster and more cost effective quality assurance (QA) system. The standard technique relies on the use of film for two-dimensional dose distribution verification. Although film is considered the gold standard and is widely used for this purpose, the procedures involved are relatively lengthy, labour intensive and costly for a multiple field IMRT verification.

Abstract:
An amorphous-Selenium (a-Se) based portal detector, which uses the metal substrate as a conversion plate, is studied using Monte Carlo techniques. The optimal thickness and material of the metal plate and a-Se thicknesses are investigated by modelling dose deposition in the a-Se layer for a 6 MV exit beam. Simulations of Detective Quantum Efficiency DQE(f) show that although DQE(0) increases with metal thickness up to $d sb{max},$ there is a cross-over near 1 cycle/mm which indicates that smaller metal thicknesses are more useful to visualize edges and small objects.

Abstract:
The problem of charge creation by x-rays in amorphous selenium (a-Se) is studied. A quantitative theory is developed which includes collective and single electron-hole pair excitations by a passing electron. This theory is incorporated into a Monte Carlo code to calculate track structures in a-Se. The initial positions of the electron-hole pairs along these tracks are used to study the fraction of pairs which recombine versus incident x-ray energy and applied electric field. The experimentally-observed energy dependence of recombination is attributed to a spur size which is dependent on the ve

Abstract:
Introdução: elastografia ultrassônica é um método não invasivo validado e rotineiro para a determinação indireta do grau de fibrose hepática e em investigação para predizer a presença de varizes esofágicas.

Na revisão de literatura que realizamos, observamos que há escassez de estudos de acurácia diagnóstica em pacientes com hipertensão portal não cirrótica. Objetivos: avaliar a acurácia diagnóstica das técnicas de elastografia hepatoesplênica (transitória por FibroScan e ARFI) para predizer a presença de vari
